Probabilities are used to determine the chances of an event.
The probability of a student taking a yoga class or a pilate class i 0.79
The given parameters are:
![\mathbf{P(Yoga) = 0.70}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28Yoga%29%20%3D%200.70%7D)
![\mathbf{P(Pilate) = 0.60}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28Pilate%29%20%3D%200.60%7D)
![\mathbf{P(Yoga\ and\ Pilate) = 0.51}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28Yoga%5C%20and%5C%20Pilate%29%20%3D%200.51%7D)
The probability of Yoga or Pilate is:
![\mathbf{P(Yoga\ or\ Pilate) = P(Yoga) + P(Pilate) - P(Yoga\ and\ Pilate)}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28Yoga%5C%20or%5C%20Pilate%29%20%3D%20P%28Yoga%29%20%2B%20P%28Pilate%29%20-%20P%28Yoga%5C%20and%5C%20Pilate%29%7D)
Substitute known values
![\mathbf{P(Yoga\ or\ Pilate) = 0.70 + 0.60 - 0.51}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28Yoga%5C%20or%5C%20Pilate%29%20%3D%200.70%20%2B%200.60%20-%200.51%7D)
![\mathbf{P(Yoga\ or\ Pilate) = 0.79}](https://tex.z-dn.net/?f=%5Cmathbf%7BP%28Yoga%5C%20or%5C%20Pilate%29%20%3D%200.79%7D)
Hence, the probability of a student taking a yoga class or a pilate class i 0.79

Simplify both sides of the equation
3x+1/10 = x+ -1/7
Subtract x from both sides
3x+1/10 -x = x+ -1/7 -x
2x+1/10 = -1/7
Subtract 1/10 from both sides
2x+1/10 - 1/10 = -1/7 -1/10
2x= -17/70
Divide both sides by 2
2x/2 = -17/70/2
x= -17/140
decimal x will equal -0.121
